For those machines with wapf=4, BIOS won't update the wireless LED, since wapf=4 means user application will take in chage of the wifi and bt. So, we have to update wlan LED status explicitly.
But I found there is another wireless LED bug in launchpad and which is not in the wapf=4 quirk. So, it might be better to set wireless LED status explicitly for all machines.
